| 摘要 |
Disclosed are substituted 7-membered to 12-membered cycloalkanes comprising terminal groups, especially chloride atoms, on tertiary ring carbon atoms, a method for the production thereof, and the use thereof as cationic polymerization initiators, particularly for cationically polymerizing isobutene. Preferred compounds are 1,4-dichloro-1,4- dimethylcyclooctane, 1,5-dichloro-1,5-dimethylcyclooctane, and mixtures thereof. Said compounds are produced by adding hydrocarbon to adequately substituted cycloalkapolyenes.
